GRINDING AND MIXING- AND AGITATING IEACHINE AND THE LIKE.

Application filedFebruary 25, 1921.

To all whom it may concern:

Be it known that I, Parr Bonn Jaecnn, a subject of the King of GreatBritain, residing at London, England, have invented certain new anduseful Improvements in and Relating to Grinding and Mixing and AgitatingMachines and the like, of which the following is a specification.

The present invention relates to improvements in and relating togrinding and mixing and agitating machines and the like, and beingparticularly applicable to ball and like grinding and mixing andagitating machines and the like, as will be hereinafter described in theapplication.

The present invention is essentially characterized by a tandem system oftwo or more receivers revolving alternately in opposite directions on ahorizontal or substantially horizontal axis, fixed partitions betweenthe receivers serving as common heads or closures to the adjacent endsof the receivers, provision being made for end discharge from receiverto receiver and a final discharge at the opposite end from where thefeed enters.

The pass from one charged receiver to another may be controlled by astraight or curved plate slide normally closing an opening in a fixedpartition which serves as a common head or closure to adjacent ends oftwo receivers.

The receivers may be conveniently and advantageously mountedperipherally in suitably supported bearings which may have inwardlyprojecting radial flanges or like to co-operate with outwardlyprojecting radial flanges or like on the receivers for connecting thereceivers end to end, also to like bearings at the feed and dischargeends of the system.

Drive of the receivers so that they revolve alternately in oppositedirections may be variously effected, Gear wheels which drive toothedrings on the receivers and are alternately driven by open and crossedbelts respectively from a common main shaft to separate counter shaftsserves well.

In mounting the tandem system of receivers there may be a general slopeof the system towards the discharge end.

The method of feeding may be by a hopper i and sloping passage throughthe teed-end or head of the system, and in some cases there may beprovision for feeding as by a hopper and passage through one or more orany of the partitions of the system, such additional Serial No. 447,861.

feeding provision stepping in for example it it is desired to add someother material or materials at some intermediate stage or stages in thetreatment.

The system may be adapted in well known or appropriate manner for use asa tube mill, or as a ball or like mill or mixer or agitator, or as acombination of a ball and tube mill, or, otherwise, the tumbling of thematerial due to revolving the receivers alter nately in oppositedirections may sufiice either alone, or in conjunction with means, as asuitable liner, or radial or oblique ribs or shelves, to eitect adesired mixing or incorporating operation.

The following is an example of mixing concrete by a machine under thepresent invention, firstly'the stones are fed to the machine, then thesand, and then the cement. The machine is started and sufiicient wateris then added. The stones and sand have a mill action on the cement andmixing and incorporating is accompanied by a simultaneous fine grindingaction like or similar to a tube or ball mill.

In passing from one charged chamber to another while the machine iscontinually or continuously being fed all chambers come finally underpressure so that there is a drive through all chambers in a directiontowards the discharge end and outwards to the moulds or otherwisewherever required.

The accompanying drawings shew by way of example a form of machineembodying the present invention.

In the drawings, Fig. 1 is a side view, Fig. 2 a sectional view on theline w:c of Fig. 1 showing one form of plate slide, Fi 3 is a view of avariant form of plate slide, Fig. 4c is a diagrammatic view of the drivefor the cylinders, and Fig. 5 an end view thereof.

As hown by Fig. 1 the machine comprises a tandem system of cylinders 1.2, 3 and a mounted so that the general slope of the system is towardsthe discharge end. The cylinders are mounted peripherally in suitablysupported bearings 5 having inwardly projecting radial flanges 6 whichco-operate with outwardly projecting radial flanges 7 on the cylindersfor connecting the cylinders end to end. The bearings 5 are on fixedpartitions or plates 8 which serve as a common head or closure toadjacent ends of the chambers 9 of the cylinders 1, 2, 3 and 4. Likebearings 10 are provided on the feed end plate 11 and discharge endplate 12 of the system.

Drive of the cylinders so that theyrevolve alternately in oppositedirections is effected by toothed rings 13 on the cylinders with whichengage gear wheels 14, 14:. The pin ions 14, 14 are alternately drivenby open and crossed belts 15 and 16 respectively from a common mainshaft to separate counter shafts l7 and 18.

The main feed is by a hopper 11 and sloping passage 11 through thefeed-end plate 11 of the system. Additional feeding provision isprovided by hoppers 19 and passages 20 through the partitions or plates8.

Rollers 21 rotatably carried by shafts 22 form an external bearingsystem for the cylinders l to 4, rings 23 on the cylinders bearing onthe rollers 21.

The pass from one charged chamber to another is controlled in themachine illustrated by Figs. 1 and 2 by straight plate slides 24.working in openings in the fixed partitions 8. Fig. 2 shews one slide24: in the open position whereby discharge from, for example, thecylinder 4: to the cylinder can take place. The discharge takes placethrough a screen or grid 25 provided in the slide 24, so that the sizeof the material passing from one chamber to the other is controlled, andin the case of working the mill with a filling of, for example, steelballs these are prevented from passing from one chamber tothe otherduring the passage of the material. a

Fig. 3 shews a varied form of control for the pass in the form of acurved plate slide 26 having a screen orgrid 27. r

The final discharge takes place through an outlet 28 and a slide control29 similar to the slides 24.

The slide control may be operated in any convenient Way.

Supplemental means such as ribs 30 may be provided, in addition to thetumbling of the material due to revolving the cylinders alternately in01 posite directions, for effecting a desired mixing or incorporatingopera tion. 7
